The objective of this work is to assess the discrepancy in distance between the target chosen by magnetic resonance imaging (MRI) and the final electrode placement after intraoperative microrecording in patients submitted to deep brain stimulation (DBS) for alleviating the Parkinson's disease (PD). ⋯ There is a significant discrepancy between the final physiological target after microrecording and the target chosen by MRI during surgery for alleviating PD that may induce variations or absence of clinical efficacy in parkinsonian patients submitted to the DBS surgery. Authors suggest the necessity of the microelectrode recording in order to reach the surgical target with the best clinical condition.

Throughout the world, is fully accepted that a person is dead when brain death exists. In most situations, neurological criteria permit the diagnosis of brain death, but in some instances, as when high-dose barbiturate therapy has been used, confirmatory testing are required by law. ⋯ TCD is a fast, simple and accurate confirmatory testing in the determination of brain death and its findings are not affected by high-dose barbiturate therapy. We think that TCD must be present in all hospitals where mechanical ventilation and support of patients are carried out.
